Two Reasons Why Color Shifting Inks are Used in Anti-Counterfeiting

On 15.09.14, In Security Printing, by Blake Houser

Optically Variable Inks (OVI), also known as color shifting inks, are most commonly seen on U.S. currency. For example, these inks are engraved on the bottom right-hand corner of the $10 bill.10dollarbillblog

Color shifting inks display two distinct colors on the $10 bill, green and copper, depending on the angle at which you are viewing the bill.

These inks are extremely useful as simple overt security features that deter counterfeiting. There are only a handful of manufacturers of optically variable inks, which are not easy to obtain. One of the manufacturers is Cronite, which is based in the U.S. There are other, larger manufacturers overseas.

Two great aspects of optically variable inks for securing your document are: 1) The color shifting ink is easily recognized by authenticators, who require little or no training, and 2) The document cannot be copied successfully. The copier will only be able to copy one angle of the color.

Color shifting inks can be found on the following products, but are not limited to these:

• Banknotes
• Passports
• Certificates
• Diplomas
• Tax stamps
